What is claimed is: 
     
         1 . A node apparatus in a first mobile communication network operated by a first mobile communication operator, the node apparatus comprising:
 a memory storing instructions; and   one or more processors configured to execute the instructions to:
 obtain identification information of a terminal apparatus connected to the first mobile communication network; 
 determine whether the terminal apparatus is managed by a second mobile communication operator operating a second mobile communication network different from the first mobile communication network, based on the identification information and association between terminal apparatuses and mobile communication operators; 
 when it is determined that the terminal apparatus is managed by the second mobile communication operator, perform control for reducing communication quality of the terminal apparatus to be higher than a predetermined value; and 
 when it is determined that the terminal apparatus is not managed by the second mobile communication operator, perform control for reducing the communication quality of the terminal apparatus to be lower than the predetermined value. 
   
     
     
         2 . The node apparatus according to  claim 1 , wherein
 the one or more processors are configured to execute the instructions to, when it is determined that the terminal apparatus is managed by the second mobile communication operator, perform control for enhancing the communication quality for the terminal apparatus to be higher than the communication quality for another terminal apparatus managed by the first mobile communication network.   
     
     
         3 . The node apparatus according to  claim 2 , wherein
 the control for enhancing includes priority control for raising order of priority of a packet used for the terminal apparatus to be higher than the order of priority of the packet used for the other terminal apparatus managed by the first mobile communication network.   
     
     
         4 . The node apparatus according to  claim 2 , wherein
 the control for enhancing includes band control for restricting a communication band used for the other terminal apparatus managed by the first mobile communication network to a predetermined bandwidth or lower.   
     
     
         5 . The node apparatus according to  claim 1 , wherein
 the control includes band control for restricting a communication band used for the terminal apparatus to a predetermined bandwidth or lower.   
     
     
         6 . The node apparatus according to  claim 1 , wherein
 the node apparatus is a core network node in the first mobile communication network.   
     
     
         7 . The node apparatus according to  claim 1 , wherein
 radio communication in the second mobile communication network is performed using a radio frequency band used for radio communication in the first mobile communication network.   
     
     
         8 . A control method performed by a node apparatus in a first mobile communication network operated by a first mobile communication operator, the control method comprising:
 obtaining identification information of a terminal apparatus connected to the first mobile communication network;   determining whether the terminal apparatus is managed by a second mobile communication operator operating a second mobile communication network different from the first mobile communication network, based on the identification information and association between terminal apparatuses and mobile communication operators;   when it is determined that the terminal apparatus is managed by the second mobile communication operator, performing control for reducing communication quality of the terminal apparatus to be higher than a predetermined value; and   when it is determined that the terminal apparatus is not managed by the second mobile communication operator, performing control for reducing the communication quality of the terminal apparatus to be lower than the predetermined value.   
     
     
         9 . A non-transitory computer readable recording medium storing a program for causing a node apparatus in a first mobile communication network operated by a first mobile communication operator to execute:
 obtaining identification information of a terminal apparatus connected to the first mobile communication network;   determining whether the terminal apparatus is managed by a second mobile communication operator operating a second mobile communication network different from the first mobile communication network, based on the identification information and association between terminal apparatuses and mobile communication operators;   when it is determined that the terminal apparatus is managed by the second mobile communication operator, performing control for reducing communication quality of the terminal apparatus to be higher than a predetermined value; and   when it is determined that the terminal apparatus is not managed by the second mobile communication operator, performing control for reducing the communication quality of the terminal apparatus to be lower than the predetermined value.
